1.Diving Safety Guide
1.1 Please ensure that you fully understand how to use your dive equipment
and the CR-5 dive function and what the information displayed on this
product means. If you have any questions about this product, please always
contact your CREST dealer for answers prior to your diving activity and use.
Remember, your safety is your responsibility, so please pay attention to all
details and do not ignore any signs of discomfort!
1.2 Please be sure to read and thoroughly understand the entire contents of
the CR-5 Diving Instruction Manual. Any confusion or negligence, failure to
follow the contents of the Instruction Manual, or failure to follow normal
operating practices may result in serious injury to life or even death.
1.3 The CR-5 diving function is designed for recreational diving use only,
and CREST strongly advocates that this device should not be used for
commercial or professional diving activities. Anyone engaged in commercial
or professional diving is often exposed to depths and conditions beyond
those for which the watch was designed, which may result in the occurrence
of Decompression Illness (DCI).
1.4 This product is not a substitute for formal diving education and training.
Only divers who have received formal training from a professional dive
operator and know how to operate the dive equipment should use this
product.
1.5 Each dive may carry a risk of decompression sickness and even if you
follow your dive plan or the calculations of the dive plan and dive information
shown on this product, the product cannot anticipate and measure changes
in individual physiology. Therefore, divers should try to stay within the limits
indicated by the product.
1.6 It is recommended that you seek the consent of your physician before
engaging in diving activities. There is no algorithm, formula, theorem, dive
computer or dive program that can completely eliminate the chance of
decompression sickness or oxygen toxicity. Individual physiology varies
depending on environmental factors and therefore this product cannot fully
protect you from injuries associated with diving activities.
"The best way to completely avoid injuries associated with diving
activities is not to engage in them."
1.7 This product is not guaranteed to be in full functional condition at all
times. Always carry a depth gauge, pressure gauge, timer and hand gauge
Page 4

as backup instruments and always compare your dive plan and check the
remaining residual pressure.
1.8 This product is factory tested to a depth of 100 m/330 ft and is intended
for recreational diving only. CREST strongly recommends that recreational
divers do not exceed the maximum depth of 40 m/131 ft specified for
recreational diving (air diving), or the maximum depth allowed by your dive
training, and do not use it in diving environments where you are not trained
to dive within the depth limits of your training.
"Your safety is your own responsibility, and to challenge risk is to
challenge your luck."
1.9 CREST strongly discourages recreational divers from engaging in diving
activities that require the performance of decompression, or diving above
the No Decompression Limit (NDL). Decompression diving activities require
specialist training and an adequate air supply.
As soon as you exceed the NDL or the product signals that you are
recommended to perform a decompression dwell, you should immediately
stop diving and begin a slow rise and decompression procedure. Please pay
close attention to the flashing digits, warning tone and vibration warning,
and pay attention to the ascent speed, dwell depth and time of the product,
there may be multiple recommended dwell depths and times, we suggest
you follow the instructions and complete the dwell.
1.10 This product can assist in calculating dive no-decompression limits
etc., but it does not mean that you can skip the dive planning process etc. If
your dive plan is more conservative, please always give priority to your dive
plan.
1.11 To ensure that the display of the product is correct and complete,
before each dive, you should start the product correctly and check its
functions, and make sure that the battery power is sufficient, the oxygen
concentration setting, the personalization setting, and adjust other settings
to make sure they are compatible with your dive plan.
1.12 Any diving activity undertaken prior to the first activation of this product
may result in misleading information. If the product is left on the surface and
not dived with the diver, the dive computer meter will not provide accurate
dive planning and dive information calculations for subsequent dives.
1.13 Divers must not exchange or share this product with each other, and
their internal dive information must match the original user in order to ensure
the correctness of the dive plan and dive information displayed
subsequently; their internal information cannot be transferred to divers who
do not wear it in its entirety, and it cannot be used for subsequent repeat
dives.

1.14 Before diving, please make sure that the settings of this product are
correct and fit your dive plan, e.g. the oxygen ratio of the gas to be used,
and input them into this product. Failure to personally confirm the contents
of the oxygen cylinder, or to set the correct personalized adjustment
settings, may result in incorrect calculation of the dive plan and dive
information, and in severe cases may result in the diver's life being in
danger.
1.15 The input value of the oxygen concentration percentage of this product
is only accepted as an integer, please do not remove the decimal point by
yourself when inputting. The recommended input method is the
unconditional rounding method, for example, if your cylinder measurement
is 31.8%, please input the oxygen concentration value: 32%. The decimal
point will be underestimated and will result in incorrect calculation of the dive
information, which may lead to life threatening divers.
1.16 Divers should avoid flying during the period when this product shows
the proposed no-fly countdown. You should also check that the ban is lifted
before flying. Flying or travelling to high altitude areas during the no-fly
period may significantly increase the risk of developing decompression
sickness. Please review the recommendations of the Diver Alert Network
(DAN).
1.17 This device contains a lithium battery. To avoid the risk of fire or
combustion, do not attempt to disassemble, crush, puncture, or throw the
device into a fire or leave it in water for a long period of time. If the device is
damaged and you wish to dispose of it, please dispose of it properly or
recycle it in accordance with the regulations in your area.

2.2 Charging
1. Please install the charging clip and charging cable to a USB output power
source, such as a mobile phone charger, mobile power, etc.
2. Please make sure that your power output device is a safe and qualified
product. Do not use a product from an unknown source or without safety
certification regulations.
3. After confirming that the charging clip is connected to the power source, open
the charging clip and confirm the direction of the charging point.
4. When the device is connected to the power source, the battery status will be
displayed on the screen.
5. Charging time is recommended to be about one to three hours, and may take
longer for weaker transformers.
2.3 Wearing CR-5
1. The GPS antenna is hidden underneath the screen. It is recommended to keep
the antenna pointing upwards to get a better signal when wearing it.
2. Because of the correctness of the optical heart rate component, please wear it
1-2cm behind the wrist joint.
3. Avoid wrist rotations and palm opening and closing movements that will tug on
the wrist muscles at the beginning of the measurement.
2.4 Forced Shutdown
When your CR-5 is off, just press and hold the power button at the bottom left
corner for about 15-20 seconds, the CR5 will turn off forcibly, press the power
button again and it will turn on normally. If there is no response, it is possible that
your CR-5 has run out of power. Please connect the charging clip to your watch and
let it charge for about 5 minutes and try again.
